چکیده مقاله :
شواهد تجربی در مطالعات حاکی از آن است که حضور زنان در هیأت مدیره، کمیت و کیفیت افشای عمومی اطلاعات را افزایش میدهد. در این راستا انتظار بر آن است که افزایش ترکیب جنسیتی در هیأت مدیرهی شرکتها به کاهش عدم تقارن اطلاعاتی منجر گردد. لذا پژوهش حاضر بهدنبال بررسی تجربی این موضوع با استفاده از اطلاعات مربوط به شرکتهای پذیرفته شده در بورس اوراق بهادار تهران است. در این مطالعه، اطلاعات مربوط به 173 شرکت که در طی سالهای 1386 تا 1395 در بورس اوراق بهادار تهران پذیرفته شدهاند، مورد بررسی قرار گرفته است. برای آزمون فرضیههای آماری از تحلیل رگرسیون خطی چند متغیرهی تابلویی استفاده شده است. نتایج حاصل از پژوهش نشاندهندهی آن است که بین ترکیب جنسیتی که با حضور زنان در ترکیب هیأت مدیره نشان داده میشود و عدم تقارن اطلاعاتی، یک رابطهی منفی براساس شاخصهای شکاف قیمت و اندازهی شرکت وجود دارد. نتیجهی کلی این پژوهش دلالت بر این دارد که چنانچه ابزارهای نظارتی نظیر حضور زنان در ترکیب هیأت مدیره به نحوی مطلوب و مطابق با مبانی مطرح شده در این پژوهش مورد توجه قرار گیرد، میتواند باعث کاهش عدم تقارن اطلاعاتی شود.
Empirical evidence suggests that the presence of women in the board increases the quantity and quality of public disclosure. In this regard, the expectation is that increasing the gender diversity in the board of directors will reduce information asymmetry. Therefore, the present study sought to use data about the companies listed in Tehran Stock Exchange. The statistical sample includes 173 companies that have been accepted in Tehran Stock Exchange between 2007 and 2016. Linear regression analysis of panel data was used to test statistical hypotheses. The results of the research show that there is a negative relationship between the gender diversity shown by the presence of women in the composition of the board and the information asymmetry based on the price gap and size of the company. The overall result of this research suggests that if monitoring tools, such as the presence of women in the composition of the board, are desirable and in line with the principles raised in this research, can reduce the information asymmetry.
